Kastar Hand Tools CLT-4 Cylinder Leakage Tester Dual Gauge 35 PSI

The Kastar Hand Tools CLT-4 is a professional-grade cylinder leakage tester designed to diagnose internal engine problems quickly and accurately. This dual-gauge system operates at 35 PSI to measure the percentage of cylinder leakage and help identify worn rings, leaking valves, blown head gaskets, and cracked cylinder heads or blocks.

Key Features:

• Dual-gauge design displays both input pressure and leakage percentage simultaneously
• 35 PSI operating pressure for safe and accurate testing
• Tests for worn piston rings, burnt or sticking valves, and head gasket leaks
• Helps pinpoint leak location by listening at exhaust, intake, crankcase, or radiator
• Durable construction for professional shop or DIY use
• Compatible with most gasoline and diesel engines

Cylinder leakage testing is one of the most effective methods for determining internal engine condition without disassembly. By pressurizing each cylinder at top dead center on the compression stroke, the CLT-4 reveals exactly where compression is being lost, enabling accurate diagnosis and repair decisions.
